Three people tell you they want an integration.
They may be describing three different jobs at three different depths for three kinds of specialist.
Data engineer setting up nightly ingest of new contract details from CRM into the data warehouse for revenue reporting → Integration.
System integrator setting up a webhook to send new ticket payloads into a different ticketing system while adhering to pre-defined business logic → Integration. (this is where I live)
Developer building a marketplace plug-in that lets users of one app see another app's data without leaving their screen → also Integration.
Different depths, different stakeholders, different trade-offs, still integration.
Which depth do you live at?
